Title: Method and device for discriminating area
Inventor: MORO TAKAHIRO
IPC: H04N1/40
Filed: 1992-11-02
Abstract: PURPOSE:To accurately discriminate a multi-level area and a single-level area. CONSTITUTION:When the picture elements of the upper and lower lines of a picture element under consideration are not edge (S31) and the picture element values of the picture element under consideration and the upper and lower picture elements are practically not coincident (S34), it is judged that the picture element under consideration belongs to the multi-level area (S35). While moving a comparison picture element on a line same as the picture element under consideration (S37, 40), the picture element values of the picture element under consideration and the comparison picture element are compared (S38) and even when the picture element values are coincident (S38), when the picture element values of the comparison picture element and the upper and lower picture elements do not coincide (S39) and the upper and lower picture elements of the comparison picture element are not edge (S44), it is judged that the picture element under consideration belongs to the multi-level area (S43).

Title: Fire alarm device
Inventor: SUZUKI TAKASHI
IPC: G08B17/00
Filed: 1988-11-24
Abstract: PURPOSE:To simply detect a defective sensor by measuring the sensitivity from a receiver side in a state that a fire sensor remains attached to the ceiling. CONSTITUTION:By operating a switch 21, a test use power supply voltage being higher than a power supply voltage at the time of monitoring is supplied to a fire sensor 1 from a second power source unit 23. Simultaneously, by applying a trigger to a timer circuit 24, time is counted. When the test use power supply voltage is applied to the fire sensor 1, a testing circuit of its inside operates, and a test signal is applied to a detecting element. When the test signal is applied, the detecting element outputs the same detecting signal as the time when a fire phenomenon is detected, and lines 3, 4 are allowed to conduct. When a current detector 20 of a receiver 2 detects it, the timer circuit 24 stops counting of time, and outputs a count signal at this time to an indicator 25. The indicator 25 converts a sensitivity level from the count signal and displays it.
